Abstract: An alkylating process such as hydroalkylating process comprising feeding a gas material and a liquid material into the reactor, distributing the liquid material to the upper surface of a bed of a catalyst substantially uniformly. The substantial uniform distribution of the liquid material to the upper surface allows for substantially uniform distribution of liquid reaction medium in the bed, thereby preventing hot spot and undesirable continuous liquid zone, both of which can cause the production of undesired by-products. The invention is particularly useful for the hydroalkylation reaction of benzene in making cyclohexylbenzene, which can be used for making cyclohexanone and phenol.
Abstract translation: 烷基化方法例如加氢烷基化方法，包括将气体材料和液体材料进料到反应器中，将液体材料基本均匀地分配到催化剂床的上表面。 液体材料向上表面的显着均匀分布允许液体反应介质在床中的基本上均匀的分布，从而防止热点和不期望的连续液体区域，这两者都可能导致不期望的副产物的产生。 本发明特别可用于苯在制备环己基苯中的加氢烷基化反应，其可用于制备环己酮和苯酚。

Abstract: A process for activating a hydroalkylation catalyst in a first state comprising an acid component and a hydrogenating metal component, including: (i) treatment at a temperature of at least 120° C. in the presence of hydrogen for a first duration to produce a catalyst in a second state having a first hydroalkylation activity; (ii) contacting the catalyst in the second state with an aromatic compound and hydrogen under a hydroalkylation condition effective to convert at least part of the aromatic compound to a cycloalkylaromatic compound and produce a catalyst in a third state; and (iii) treating the catalyst in the third state at a temperature of at least 160° C. in the presence of hydrogen but advantageously in the substantial absence of the aromatic compound for a third duration to produce an activated catalyst in a fourth state having a third hydroalkylation activity greater than the first hydroalkylation activity.
